So long, and thanks for all the protons! September 29, 2011

This is a picture of the Cockroft-Walton at Fermilab’s Tevatron. This is where it all starts.

It isn’t that much of an exaggeration to say that my career started here. You are looking through a wire cage at one half of the Cockroft-Walton – the generator creates a very very very large electric field that ionizes Hydrogen gas (two protons and two electrons) by ripping one of the protons off. The gas, now charged, can be accelerated by an electric field. This is how protons start in the Tevatron.

And that is how most of the experimental data that I used for my Ph.D. research , post-doc research, and tenure research started. Basically, my career from graduate student to tenure is based on data from the Tevatron. The Tevatron delivers its last beam this Friday, at 2pm Central time (the 30th).

I’ll miss working at Fermilab. I’ll miss working at DZERO (the most recent Fermilab experiment I’ve been on). I’ll also miss the character of the experiments – CDF and DZERO now seem like such small experiments. Only 500 authors. I feel like I know everyone. It is a community in a way that I’ve not felt at the LHC yet. And I’ll miss directly owning a bit of the experiment – something I joined the LHC too late to do. But most of all I’ll miss the people. True – many of them have made the transition to the LHC – but not all of them. For reasons of travel, or perhaps retirement, these people I’ll probably see a lot less over the next 10 years. And that is too bad.

I’ll remain connected with DZERO for some time to come. I’m helping out with doing some paper reviews and I’m helping out with data preservation – making sure the DZERO data can be accessed long after the experiment has ceased running.

Tevatron. It has been a fantastic run. You have made my career. And I’ve had a wonderful time with the science opportunities you’ve provided.
